Abstract: 972,994. Valves. WEBSTER ELECTRIC CO. May 8, 1961 [June 16, 1960], No. 16684/61. Heading F2V. [Also in Division F1] A four-way valve comprises a movable spool valve member 12 in a housing having an inlet port 18, two motor ports 17, 19 and an exhaust port 16. The passages 32, 48, and 51 leading from port 17 to a motor 18 contain a check valve, which may be a ball 50, loaded by a spring 53 towards its seat 52. With the spool valve 12 in the position shown, fluid is fed to the motor and opens the check valve in the normal manner. When the spool valve is moved to the right, the motor port 17 is connected to the exhaust 16 and the inlet 18 is connected to the second motor port 19. Fluid flows to the motor port 19 and through passages 33, 45 to a bore 58, housing a pilot valve member 60. The valve member 60 has a groove 64 and ports 63 open to a regulating port 71 through which the fluid flows to act on the valve member 60 urging it to the left. When the pressure is sufficient the valve moves to the left and, through rod 68, opens the check valve 50 to allow return flow. Once the check valve is opened, the force necessary to hold it open is reduced and the valve 60 opens a passage 46 to an exhaust 20, to release the pressure and thus the pressure required from the pump supplying the inlet 18 is reduced. When the valve 12 is supplying pressure to the motor 28 the valve member 60 is held in the position shown by fluid in passage 32 passing through recess 47 and passage 49 to act on the head 61 of the valve 60. Specifications 677,800 and 837,531 are referred to.
